A 70-year-old man suffered serious injuries when his plane crashed into a home Monday morning in Cottonwood, police said.

The pilot had managed to exit the plane on his own, according to Cottonwood police Sgt. Monica Kuhlt. She said the plane, a single-engine Bonanza Beechcraft, was on fire in the backyard of the home by the time officers arrived.

The pilot was transported to the Maricopa Burn Center. His condition was not immediately available.

Kuhlt said the house sustained minimal damage, and no one was home at the time.

The cause of the crash is unknown. Kuhlt said the pilot told crews his engine had stopped.
